Suppose a random sample of 800 adults will be surveyed on whether they have received phishing emails to determine recent trends. Use this information to answer questions 1 through 3.
1. Give the mean and standard deviation of the sample distribution of hatp. Give your answers in decimal form. (Example: 0.398)
Mean (Round to two decimal places) =
Standard deviation (Round to three decimal places) =
Determine the probability that more than 45% of those in a survey would have received a phishing email.
